Cyclists more likely to develop arthritis in knees according to research

This is going to sound very strange, but I spent 40 minutes squatting yesterday. Oh dear!
As for the article though, there doesn't seem to be an explicit statement of causality anywhere: simply that there was some correlation. As far as I am aware, correlation does not equal causation (despite comparative government large-n data studies' frequent claims)...

This article is just so far from the mark it reinforces the fact that most so called 'research' appears to be churned out as media fodder. There is no such thing as 'arthritis of the knee, or osteoarthritis' - arthritis is a catch all term for many different types of arthritis, the two main ones being rheumatoid (which is inflammation of the joint) and osteo (which is a degradation of the bone). The cause of arthritis is still largely unknown. Speaking as someone who was diagnosed with rheumatoid 30 years ago when I was 21 and at the time was left unable to walk, and who has subsequently made a full recovery and cycled probably 50k miles since, cycling has been a godsend. I can't run much or walk any distance but I can keep fit by cycling.

"According to the study people who cycled for more than 30 minutes daily were two times more exposed to the risk of developing arthritis of the knee. And individuals who spent more than 30 minutes a day squatting were at 1.5 times increased risk." Absolute nonsense - given that the cause of arthritis is largely unknown, how did they deduce this? Did they take into account the overall health benefits of regular low impact exercise? Did they assess it against say jogging? And who spends 30 minutes a day squatting??? Bah ...

Oh well at least I now know I'll need help when I'm older.
Cycling, Squash, Skiing, my knees must be on their way out soon.

Fringe and Mr. Sock are on to something, it's the damned squatting...that's it no more gratuitous squatting for me, it's official!

If normal cycling is bad then downhill MTB racing or BMX racing must be be particularly bad for the knees, given all the impacts of jumps.

I'm 47 and I can still walk unaided.

maybe he balances it all out by never ever squatting. Have you seen Lance squat? Me neither

Define "middle aged". Armstrong is 38, i'd consider that to be pretty middle aged and he doesn't seem to be doing too badly with regards to the cycling...

Hmm so what about all those runners who take up cycling when their knees go?

.

still, when we cant stand or use our legs to cycle we can get one of those hand bicycles, or at least till our wrists seize up. (or maybe they have but lets not go there!)

Christ, this cycling lark has a lot to answer for...

Not only will I not be able to perform sexually due to it, but I won't even be able to stand up!

Oh well, both those things are over-rated, I'll take my chances...

better stop all that squatting then?!
